Cognitive Tools
• Tools that enhance the cognitive powers of human beings during thinking, problem solving and learning
• Consider the analogy of how physical tools extend our physical limitations– Hammers: pounding things– Saws: cutting things– Cars: move about quickly

Database or Spreadsheet?
• The difference between a database and a spreadsheet has been blurred in recent years
• Each can do pretty much what the other can
• However, each still has its strengths (affordances)– SS: Numeric relationships– DB: Classification of data

Cognitive Tool Assignment
• Develop a brief lesson plan that integrates either a database or a spreadsheet in a meaningful way to accomplish the learning goals of a lesson.
• The computer tool should be central to your lesson plan such that the lesson would not be possible without the tool.
• The goal of this lesson plan is not to teach the tool, but to use the tool to help teach about the content.
• The lesson plan is accompanied by at least one sample/example of the computer tool "at work" in your lesson.

Cognitive Tool Assignment
• Use the tool to tackle a difficult concept or principle– If it’s easy to understand already, there is no need
to use a cognitive tool
• Think Affordances– What is it about the content that makes sense to
use that tool?• Spreadsheets: Understanding numeric relationships• Databases: Understanding categorical relationships

Cognitive Tool Example
• I have been doing this activity with my second grade students in which we get a small bag of m&m's and estimate the number inside and how many of each color. After we recorded our answers we would open the bags and count them to see where we were in terms of our estimates. We would then chart our results. This activity with excel allows students to focus on making the comparisons between the company estimates and their own. They do not need to spend time drawing charts and coloring them in. They can spend all of their time thinking.

Cognitive Tool Example
• The idea behind this project is to verify truth in packaging. The students will bring in specific brands and sizes of potato chips. We will number each bag for identification. They will then weigh the packages using sensitive scales in the lab to determine if there are differences in the actual weight.
• As a secondary activity, once the basic one is done, each student would open a designated package and count the chips. They will input that number into the spreadsheet and will determine whether there is a correlation between the weight and the number of chips.

Cognitive Tool Example
• Each year my students build their own derby cars. We roll them down an inclined plane and measure the distance. Each student “gets” three rolls and we take the average. My students are sixth graders and not all of them are quick or very good with math. I found that by using the Excel program, students could enter their three distances and the computer will average it for them.

Cognitive Tool Example
• For a different education course I developed a science lab on evaluating the effects of fertilizer on plant growth response. However, what I did not include was a means for the students to process their data. For this cognitive tool project, I used Microsoft Excel to develop a spreadsheet for them to enter data as well as analyze their findings. After analyzing the data I would have students make graphs to better help them understands their findings. In the past, I have used Excel to analyze my own data. However, this project help me to format a spread sheet beyond analyzing data but to design it to enhance student learning and critical thinking.

Cognitive Tool Assignment
• Submit a brief lesson plan/description (as a word doc) and your SS or DB as separate files to the “cognitive tool” assignment on WebCT.
• What are your ideas? I will use the rest of class time to discuss your ideas.
